Historical Chicago 311 Tree Debris Removal Requests

January 2011 onward records of tree debris removal requests made to Chicago's 311 system. The dataset includes open and completed requests, managed by the Department of Streets and Sanitation, with daily updates. It captures service request details, location coordinates, and administrative boundaries.

Use Cases

• Track request resolution timelines by comparing Creation Date and Completion Date columns.
• Assess service request volume and status distribution across Police District or Ward administrative boundaries.

Strengths

• Includes geospatial coordinates (Latitude, Longitude) and multiple administrative boundaries (Ward, ZIP Code, Community Area).
• Covers a long temporal range from January 1, 2011 onward.

Limitations
